The STRC Wraith Aluminum 17mm Hex Conversion Kit takes your Wraith from puny little crawler, to bone crushing monster! Simply combine this kit with a set of 1/2 offset 17mm Hex wheels and monster truck tires, and give your Wraith or Deadbolt a wider Monster Truck like stance. The system uses an inner lock-nut to hold the 17mm hex adapter to the Wraith axle, and 17mm hex lock-nut to hold down the larger monster truck tires. Open up a whole new range of tire selections and take performance and appearance to another level.
